Traffic Safety Assessment Method for Urban Road Intersection and Its Countermeasures

Aimed at the deficiencies and shortcomings in traffic safety assessment of urban road intersection by using statistical data of historical accidents at home and abroad,a new traffic safety assessment method for urban road intersection,with traffic conflict techniques and gray theory as the basis,was firstly put forward with consideration on the characteristics of road traffic safety management in China. Then,with this method,the traffic safety state of 48 intersections in Weifang City of Shandong Province was evaluated,and safety-improving countermeasures were presented according to the evaluation results. The demonstration shows that this method can effectively evaluate the traffic state of urban road intersection and obtain satisfactory results.
